Warning Serious problems might occur if you modify the registry incorrectly by using Registry Editor or by using another method. These problems might require that you reinstall the operating system. Microsoft cannot guarantee that these problems can be solved. Modify the registry at your own risk.

To enable the improved performance for duplicate broadcast data received in LBFO, please add the follow registry subkey:
  1. In Registry Editor, locate and then select the following registry subkey:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\MsLbfoProvider\Parameters\NdisAdapters\<GUID>
  2. Press and hold (or right-click) <GUID>, select New, and then select DWORD (32-bit) Value.
  3. Name the new registry entry as DropStandbyReceive.
